  • Patent number: 10723264
    Abstract: An information presentation apparatus is provided. A light emission device and a HCU are mounted on a vehicle as the information presentation apparatus. The light emission device is arranged on an instrument panel, and displays at least one light emission spot in a linear light emission area arranged to extend in a width direction of the vehicle. The HCU acquires monitoring information including at least position information of the risk target detected by the peripheral monitoring device, and calculates a risk level of the risk target, detected in a traveling direction of the vehicle, based on the monitoring information. When detecting a plurality of the risk targets, the HCU selects one of the risk targets having a highest risk level as a highest risk target, and displays the light emission spot, indicative of a direction of the highest risk target, in the linear light emission area.

  • Patent number: 10571875
    Abstract: To provide an electric valve control device capable of preventing a delay at the time of starting a control of an electric valve by shortening a standby time of an air conditioner or the like when power is input again or a sleep mode is cancelled and an electric valve device including the same. After receiving a power-off signal predicting a power-off operation of an electric valve 9 or a sleep transition signal predicting a sleep mode transition operation thereof from an outside, (current) valve opening degree information at the time of stopping an operation of the electric valve 9 is stored in an EEPROM (a nonvolatile storage unit) 11c. At the time of inputting power again or cancelling a sleep mode, the current (immediately precedent) valve opening degree information stored in the EEPROM 11c is read from the EEPROM 11c to resume a control of the electric valve 9.

  • Patent number: 10549655
    Abstract: Forward tilting of a seat back and pushing of the seat forward allow fixation between an upper slide and an upper slide rail to be released, thereby allowing the upper slide to reach a tip end position of the upper slide rail. With this structure, a lower lock mechanism releases fixation of a lower slide to a lower slide rail and a vertical slide lock mechanism fixes the upper slide and the lower slide. Further, pushing the seat back toward a seat front side allows the lower slide integrally provided with the upper slide to move to a tip end position of the lower slide rail.
